Previous times down this slope:
* UK internet filters for child porn -> opt out filters for regular porn (ISPs now have a list of porn viewers) + mandatory filters for copyright infringment
* Google drive filters for illegal content -> Google driver filters for copyrighted content
* iCloud data is totally protected so it's ok to require an apple account -> iCloud in China run by government controlled data centers without encryption
* Protection against malware is important so Windows defender is mandatory unless you have a third party program -> Windows Defender deletes DeCSS
* Need to protect users against malware, so mobile devices are set up as walled gardens -> Providers use these walled gardens to prevent business models that are bad for them
